Airworthiness Directives; Boeing Model 747 and 767 Series Airplanes Equipped With General Electric (GE) CF6-80C2 Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 747 and 767 series airplanes. This action requires revising the FAA-approved Airplane Flight Manual (AFM) to prohibit the use of certain fuels, and either replacing the existing placard on the door of the fueling control panel with a new placard; or replacing all dribble flow fuel nozzles (DFFN) with standard fuel nozzles, which terminates the requirements for a placard and AFM revision. This amendment is prompted by a report of an engine flameout during certification testing due to the use of JP-4 or Jet B fuel. The actions specified in this AD are intended to prevent such engine flameouts and consequent engine shutdown.

Models747, 767

Part-conditional — 9331M72P33, 9331M72P34, 9331M72P41.

Applies to Model 747 and 767 series airplanes equipped with dual fuel flow nozzles (DFFN's) bearing General Electric part number 9331M72P33, 9331M72P34, or 9331M72P41, to prevent engine flameout from use of JP-4 or Jet B (wide-cut) fuel. Requires AFM revision restricting wide-cut fuel use, and either placarding the fueling control panel or replacing the DFFN's with standard fuel nozzles per Boeing Alert Service Bulletin 747-11A2052 or 767-11A0031 (both dated September 11, 1997), as applicable; installation of the listed GE part-numbered DFFN's is prohibited unless the placarding requirement has been accomplished.

Whether AD 97-22-04 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 97-22-04 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
